Among these, beau's and peas are important food-plants, while clover, vetches, peas, meli- lot, alfalfa, lucerne, cow-peas, etc., are valuable forage crops, cover-crops, and green manures. Many of the exotic species are of commercial importance. ' The ar- boreal forms furnish structural timber and cabinet woods. Many also furnish dye-stuffs, rubber, balsams, oils, etc., and some are cultivated for ornamental pur- poses. In respect to the character of the flowers, the family is divided into three subfamilies In the large subdivision to which the ornamental species of Mimosa ind Acacia belong the flowers are sniill and legular and often clustered in sphericil ii II n_ b( il The stamens are free or united inti> i tnl m I inu h f\erted In the second subfamilv the ri hi i u u ll\ u regular with the upper petal folded mil 1 ihi ihiis in the bud.

The keel encloses the stamens and pistil, the latter being often bent at right angles to the ovary, or coiled. The stamens are either free or they form a tubular sheath surrounding the ovary. Often the upper one alone is free, leaving a slit along the upper side of the sheath (Fig. ). These flowers are often dependent on in- sects for pollination, a fact which is of great importance
